Is it 8:00 yet?
Roy, I have not sprayed it. Did not want to thin it, so I brushed it on.
Ritchie, as far as I can tell it does not have a shelf life. The only epoxy's I have had go bad are Smooth-On with the slow hardeners. I've got some G-1 that's close to 20yrs old, just used some the other day, no problems.
